Scene zoom does not work with pixel art

The scene zoom aliases all of the hard edges. It would be nice if we could make it render as nearest-neighbor, which would allow pixel art to work at a 1:1 scale with only a zoom in the scene. Currently you have to scale up all of the assets you are working with, so that they do not get blurry when looked at. These means you have to scale the art down, to work on it, and then scale it back up to use character animator.
